Hi,
Not sure it's available but you can use the following Python expression to
add the functionality
@qgsfunction(args='auto', group='Layout')
def get_page_format(layoutname, pagenumber, feature, parent, context):
layout = QgsProject.instance().layoutManager().layoutByName(layoutname)
page = layout.pageCollection().page(pagenumber - 1)
return QgsApplication.pageSizeRegistry().find(page.pageSize())
and calling it with
get_page_format('demo', @layout_page)
Regards
Thomas Gratier
